Abstract
A water heating appliance includes a heat exchanger that draws heat from process air and delivers the heat to a heat exchange media. The heat exchanger has a polygonal cross-section defining a first area. The water heating appliance also includes a blower that delivers the process air through the heat exchanger. The water heating appliance further includes a funnel that directs the process air from the heat exchanger to the blower. The funnel manages an air pressure of the process air to be consistent within the heat exchanger, and the funnel regulates the air pressure of the process air to decrease evenly and consistently between a downstream surface of the heat exchanger and a port that directs the process air into the blower.
